This invention relates to machines for use in attaching soles to shoesby cement, either preliminarily as in sole laying or permanently as inthe manufacture of compo shoes, and is illustrated herein as embodied ina machine particularly intended for use in cement attaching soles in themanufacture of compo shoes.

Machines for use in cement attaching soles to shoes are disclosed in mycopending application for Letters Patent of the United States, SerialNo. 352,278, led April 3, 1929, and in the United States Letters PatentNo. 1,897,105, granted February 14, 1933, on the application of MiltonH. Ballard. The machine disclosed in the patent, which embodies many ofthe features of the invention of the above-mentioned application, hasgone into extensive commercial use and has given general satisfaction.It is an object of the present invention to provide a still furtherimproved machine for use in cement attaching soles to shoes.

The majority of the shoes manufactured by the compo process are Womensdress shoes of light weight and dainty appearance. The shank porv tionsof the soles of such shoes are usually reduced substantially to afeather edge and are convex. The edges of the forepart are also somewhatreduced and should hug the upper closely so that, with the close edgetrimming which is practiced in the manufacture ci such shoes, the edgeof the sole at the shank will be practically invisible and at theorepart will be quite inconspicnous when the shoes are worn.

Sole attaching machines of the type disclosed in kthe application andpatent referred to above are provided each With a duid-filled pad memberarranged to receive a properly cemented and prepared sole` and shoe and,in cti-operation With a suitable abutment or abutments, to apply soleattaching pressure. In order that the same pad member may be used withsatisfaction on diiferent sizes and styles of shoes its top or soleengaging surface is substantially ila't transversely, the sole attachingpressure being relied upon to distort the sole receiving surface of thepad so that it will press substantially uniformly over the whole of thesurface of the sole. Since, as pointed out above, the shank portion ofthe sole may be convex transversely to a substantial extent it followsthat when the sole is first placed on the surface of the pad member theedges of the shank portion of the sole may be spaced a substantialdistance from the surface oi the pad. lt is an object or the inventionto provide means by which the preliminary pressure, which precedes `thellal shoes.

The machines of the application and patent referred to above areprovided With fingers or feelers arranged to engage and be positioned bythe edge of the sole and to control additional fingers by which the shoeis positioned relatively to the sole on the pad member. The rubbersoleengaging Walls of the pad members exhibit a tendency to becomeslightly concave after they have been used for a time, so that it ispossible for an operator to place a sole on the pad in such a mannerthat it will escape from or not be properly engaged by the sole engagingngers by'reason of the sole being positioned in this depression oi" theWall of the pad. It is another object of the present invention to obvateall possibility oi' this diiliculty and this is accomplished, asillustrated herein, by slightly bulging the sole-receiving wall of thepad at the time that the fingers are brought into operation.

The depth which a shoe needs to be sunk into a pad member in order tosecure proper contact of the pad member with the sole of the shoe variesconsiderably with different sizes and styles of lt is, therefore, afurther object of the present invention to provide means by which thepreliminary pressure will be uniform and unvarying regardless of theextent to which the shoe is sunk into the pad.

While the invention is illustrated herein as embodied in a machinedeveloped for use in cementY attaching soles to shoes it should be notedthat in various of its aspects it is not limited'to embodiment in such amachine. It could, for example, be embodied in a machine for use in solelaying or direct pressure leveling as performed in the manufacture ofshoes the soles of which are permanently attached by stitching.

With the above and other objects and features in View the invention willnow be described with respect to the accompanying drawings and' showingthe parts with the machine idle or at rest, Fig. 4 showing the partsduring the application of the preliminary pressure, Fig. 5 showing thepartsv at the conclusion of the application of the preliminary pressure,and Fig. 6 showing the parts while the final pressure is being applied;

Fig. 7 is a detailed view of a toggle mechanism which serves to connectthe two weights by which the pressure is applied; and

Figs. 8 and 9 are fragmentary views showing details of a safety deviceby which premature application of the final pressure is prevented, Fig.8 showing the parts in position to permit and Fig. 9 in position toprevent application of the nnal pressure.

The present invention is illustrated herein as embodied in a machine ofthe character disclosed in the Ballard Patent No. 1,897,105 referred toabove. Many of the details of the machine are of no importance as far asthe present invention is concerned and for such portions of the machineas it has not been found necessary to describe or illustrate hereinreference may be had to that patent.

The illustrated machine is provided with a table 20 supported by legs 22and arranged to receive a pad box 24 (as best shown in Figs. 1 and 2) bywhich a shoe 26 and a sole 28 (Fig. 5) may be held clamped forciblytogether while cement by which the sole is to be attached to the shoesets. The machine is provided with means for positioning the toe end ofthe shoe relatively to the sole before the clamping pressure is applied,as indicated generally by the reference character 30 in Fig. 1, whichmeans, preferably and as illustrated, is of the character described inmy copending application Serial No. 352,278. Means is also provided forpositioning the heel end of the shoe relatively to the sole as indicatedgenerally by the reference character 40. Preferably and as illustratedthe heel-end positioning means is of the type disclosed in my saidapplication, and more specically of the character disclosed in mycopending application for Letters Patent of the United States Serial No.414,516, filed December 16, 1929 to which reference 'may be made for adetailed disclosure of that mechanism. Briefly, the toe end positioningmechanism 30 comprises sole engaging ngers or feelers 31 and shoeengaging fingers 32 mounted on a carriage 33 by which they are movedfrom inoperative to operative position through the medium of a weight 34connected with the carriage 33 by a cable 35 upon the tripping of a foottreadle 50 to which the carriage 33 is connected by means of a cable 36and a rock arm 37 carried by a rock shaft 52 by which the treadle 50 iscarried, as best shown in Fig. 2. The heel end positioning mechanism 40includes sole engaging feelers or fingers 41 and shoe engaging fingers42 mounted on a carriage 43 connected with a weight 44 by a cable 45,the carriage 43 being connected to a portion of the mechanism of treadle50 by a cable 46 so that the tripping of the treadle 50 brings the heelend positioning fingers 41 and 42 into operative position simultaneouslywith the similar movement of the toe end positioning fingers 31 and 32.While the details of the treadle mechanism are illustrated to a largeextent, particulai-ly in Figs. 1 and 2, it will be unnecessary todescribe them herein since they are identical with the correspondingmechanism shown and described in the Ballard Patent No 1,897,105,

to which reference may be had for a more detailed description. For anunderstanding of the present invention it is only necessary in thisconnection to remember that when the treadle 50 is tripped it movesgenerally upwardly, that is, in a clockwise direction as shown in Fig.2, whereby the positioning mechanisms 30 and 40 are brought intooperation.

The pad box 24 comprises a boxlike structure 60, preferably an aluminumcasting, the bottom o which consists of a doorlike plate member 62pivoted at 64 to the member 60. A rubber pad or bladder 66 is containedin the boxlike member 60. A plate 68, secured to the casting 60,overlies the marginal portion of the bladder 66 and preve-nts its upwardmovement when the plate 62 is forced upwardly to apply sole attachingpressure. In order to prevent upward movement of the shoe when the soieattaching pressure is applied, the casting carries a pair of yokes 70and 72 positioned over the forepart and the heel portion receiving areasof the bladder 66. As illustrated the yoke 70 carries an abutment member74 arranged to contact with the forepart of the shoe while the yoke 72,which is pivoted for swinging movement into and out of operativeposition, carries an abutment 76, best shown in Fig. 5, arranged toreceive the cone of the last. These abutments may be moved downwardly toapply preliminary pressure to the shoe and the sole on the pad box 24 bymechanism illustrated generally at in Figs. 1 and 2 and operated by thedepression of a treadle 82, all as fully described in said BallardPatent No. 1,897,105.

The mechanism so far described forms per se no part of the presentinvention and it has, therefore, been described as briefly as is thoughtto be consistent with a clear understanding of its relation to the novelmechanism which will now be described.

Referring now particularly to Figs. 2, 3, 4, 5, and 6 it will be seenthat a plunger 90 is mounted for vertical sliding movement in a boreformed in the table 20, the upper end of the plunger being spacedslightly from the doorlike member 62 of the pad box (as shown in Fig. 3)when the machine is in its idle inoperative position. The lower end ofthe plunger engages the forward end of a lever 92 fulcrumed at 94 to theframe of the machine. The rear end of the lever 92 is pivoted at 96 to adepending link 98 the lower end of which is pivoted at 100 to a rock arm102 secured to a rock shaft 104 having suitable bearings in the frame ofthe machine and carrying also a longer forwardly extending rock arm 106from which depends toggle mechanism 108 shown in detail in Fig. 7. Aweight 110, which is utilized to supply the preliminary pressure, is

also pivotally connected to the forward end of the arm 106 while aheavier weight 112 which, together with the weight 110, applies thefinal pressure is carried by links 115, 117 (Figs. 2 and 4), secured at113 both to the lower end of the toggle 108 and to the forwardlyprojecting end i of a bell crank lever 114 fulerumed at 116 on the frameof the machine and carrying also a shoe 118 engaging an eccentric 120fast on a shaft 122. In a machine of the character illustrated,

and having the various lever arms of about the sure of about 15 to 20pounds to the square inch 1.,,

and a iinal pressure of about 60 to 80 pounds to the square inch onwomens shoes. Y l

The toggle 108 comprises upper and lower links 130 and 132 respectively,(Figs. 3 to 7) the former being carried by a stub shaft 134 projectinglaterally from the forward end of the lever 106. Secured to the upperend of the lower toggle link 132 is a stub shaft 136 to which the lowerend of the upper link 130 is pivoted while the lower end of the link 132receives the stub shaft 113. rhus it will be seen that the toggle 108forms a connection between the two weights 110 and 112 which whenstraightened permits one weight to be carried by the other but whichpermits the two weights to be supported independently of each other whenthe toggle is broken. At times during the operation of the machine theweight 110 is supported from the weight 112 by the straightened toggleas shown in Fig. 3.

The toggle breaks to the left as shown in Figs. 3, 4, 5, 6 and 7.Accordingly, the lower toggle member 132 is provided with a projectingportion 138 engaging a surface 140 of the upper toggle member 130 asbest shown in Fig. 7 and limiting the movement of the stub shaft 136 tothe right as the toggle is straightened, to a position slightly beyondthe dead center. To prevent inadvertent displacement of the dead centerto the left of the line joining the axes of the stub shafts 113 and 134,while the weight 110 is supported by the straightened toggle from theweight 112, a spring pressed plunger 142 is housed in the upper togglemember 130 and has a lower V-shaped end 144 adapted for engagement withan inclined surface 146 formed on the lower toggle member 132. A pin 148carried by the plunger 142 is located in a slot 150 formed in the uppertoggle member 130 thereby preventing rotation of the plunger 142 andholding it at all times in such position that one of the surfaces of itsV-shaped end 144 is in position to engage with the surface 146 of thelower toggle member 132 when the toggle is straightened. Thus it will beseen that in order to break the toggle it is necessary vto exertsuicient force to cam the plunger 142 upwardly a short distance againstthe compression of its spring.

A lever 160, having a U-shaped portion straddling the lever 92, isfulcrumed on the shaft 94 for movement relatively thereto. One arm ofthe lever 160 is pivoted at 162 to a long downwardly and rearwardlyextending link 164. the lower end of which is pivoted at 166 to a rockarm 168 fast upon the shaft 52. the construction being such that whenthe treadle 50 is tripped and moves upwardly in a clockwise direction asviewed in Fig. 2, the link 164 will move downwardly, rocking 'the lever160 in a clockwise direction. This clockwise movement of the lever 160is'eiective to break the toggle 108, the lever 160 being provided forthat vpurpose with an arm 170 carrying a pin 172 which, when the partsare positioned as shown in Fig. 3 with the toggle straightened, issubstantially in engagement with the lower toggle link 132 adjacent tothe pin 136. It will be apparent, therefore, that clockwise movement ofthe levei` 160 will cause the pin 172 to push the toggle past the deadcenter, to the left as shown in Fig. 3, breaking the toggle as shown inFig. 4. This takes place as the sole engaging and shoe positioningfingers 31, 32, 41, 42 are moved into operative relation to a sole onthe pad b oX and while the heavy weight 112 is supported by the bellcrank lever 114, the shoe 118, and the eccentric 120, and causes thesmaller weight 110 to move downwardly thereby rocking the lever 106, therock shaft 104 and the lever 102 in a counter-clockwise positionasviewed in Figs. 3 and 4, and rocking the lever 92 in a clockwisedirection and causing its forward end to thrust the plunger 90 upwardlyinto contact with the plate 62 of the pad box, as shown in Fig. 4. Thiselevates the plate 62, bulging the upper surface of the bladder slightlyso that the edges of the sole which the operator `has previously placedon the bladder can by no possibility be below any portion of the surfaceof the bladder and therefore in a position where it can not be engagedproperly by the sole engaging feelers 31, 41.

The operator next places the shoe 26 on the soie 28 and swings the yoke72 into vertical position so that the abutment 76 will be' above thecone of the last. At this time, of course, the abutment 74 wili be abovethe forepart of the shoe. The operator then depresses the treadle 82,forcing the abutments downwardly and sinking the shoe and sole into thetop of the bladder far enough to cause the bladder to bulge upwardlysomewhat around the entire periphery of the shoe, as shown in Fig. 5. Asthe shoe is sunk into the bladder the pivoted plate 62 will movedownwardly, forcing the plunger 90 downwardly and lifting the weight110. From this it follows that the preliminary pressure is maintaineduniform regardless of the depth to which the shoe is sunk into thebladder, since the preliminary pressure is determined definitely by themass of the weight liO and the lever ratios, which are unvariable. Thislifting of the weight 110 moves the toggle toward, but normally notentirely to, its straightcned position, Fig. 5 showing a. normalposition at the completion of the applying of the preliminary pressure.After inspecting the shoe and sole to see that they are properly locatedrelatively to each other, the operator depresses a hand lever 176, shownin Figs. 1 and 2, and more fully described in said Ballard Patent No.1,897,105, causing the shaft 122 and the eccentric 120 to be movedthrough a single rotation and then to come to rest. As the eccentricrotates toward its middle position,`which is shown in Fig.y 6, it movesfrom the shoe 118 to release the lever 114 so that the weight; 112 canmove downwardly, straightening the toggle 108, which then serves as atension member to suspend the weight 112 from the stub shaft 134. Thusthe weight 112 is in eiiect supported fronithe weight 110 and the massof the weight 112 is added tothe mass of the weight 110, the twotogether, through Athe lever mechanism, forcing the plunger 90 and thepivoted member 62 upwardly and thereby distorting the lower wall of thebladder 60 and supplying the final sole attaching pressure. The pivotedmember 6 2 is automatically latched in the uppermost-position lto whichit is moved by mechanism indicated generally at 178 in Figs. 1

vand 2, which mechanismv is fully illustrated and disclosed in saidBallard Fatent No. 1,897,105, so that the final pressure is maintainedwhen the shaft'l22 and the eccentric 120 complete their revolution andthereby lift the weight 112 to the position shown in Fig. 3. Since thetoggle 108 has been straightened by the lowering of the weight 112, thelifting of the weight 112 also lifts the weight 110, .the spring plunger142, by reason of the engagement of one of the faces of its V-shaped'end surface with Ythe surface 146 of the toggle member 132,urging the toggle slightly past its dead center (as shown in Fig. 7) sothat it can be relied upon as a compression member.

'I'his leaves the mechanism for operating the plunger 90 in the positionin which it is shown in Fig. 3 so that the pad box 24 may be removed andanother placed in the machine.

The safety mechanism, best shown in Figs. 1, 8, and 9, is provided toprevent premature tripping of the lever 176. This mechanism comprises abent lever 200 pivoted at 202 to the frame of the machine and providedwith an adjustable stop 204 arranged for engagement with the left handside of the lever 176, and a second adjustable stop 206 arranged formovement into and out of position below the adjustable stop 208 carriedby the lever 176. It will be seen that when these parts are in thepositions shown in Fig. 9 the lever 176 can not be depressedsufficiently to throw into operation the mechanism for applying thefinal pressure. On the other hand, when the lever 200 is swung to theleft, to the position shown in Fig. 8, the lever 176 can be depressed.The lever 200 is moved from the position shown in Fig. 9 to that shownin Fig. 8 by a finger 210 secured to the weight 110. When the treadlemechanism 50 is tripped to bring the sole and shoe engaging fingers 31,32, 41, 42 into position the weight 110 moves downwardly sufficiently tobring the end 212 of the finger 210 beneath the inclined surface 214 ofthe lever 200 as shown in Fig. 9, thus causing the stop 206 to preventdepression of the lever 176, and it is not until the weight 110 has beenlifted by the application of the preliminary pressure that the end 212of the finger 210 rocks the lever 200 in a clockwise direction, as shownin Fig. 8, so that the lever 176 can be depressed to throw the finalpressure applying mechanism into operation.
